Lúcia hires a truck driver to deliver the food for her catering company. For a delivery that is M miles away, the total cost, C, in dollars, is given by the above equation. What is the meaning of the 0.4m in this equation?

55 degrees because 55+55=110 degrees

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
